The swellings which have taken place above ligatures made on the ureters of brute animals, and the instances of calculi being detained in these tubes and obstructing the passage of urine to the bladder, by retaining this fluid above them, in the human subject, sufficiently prove the usual descent of the urine from the kidney by the ureters to the bladder. When the bladder has been completely distended with urine, and can hold no more, and some obstruction in the ure- thra prevents its evacuation, the ureters, the pel- vis, and the infundibula of the kidney, will some- times enlarge to an immense size. ON THE BLADDER. The bladder of urine is well known to be the temporary receptacle of the secreted matter which is formed from the blood in the kidneys, and con- veyed thither by the two ureters.
